A roadside bomb near a U.S. military convoy wounded two U.S. troops and killed their Afghan interpreter, the U.S. military said Friday.
The attack came ahead of landmark legislative elections on Sunday, which the Taliban have threatened to subvert.
The blast occurred in central Ghazni province late Thursday, U.S. military spokesman Lt. Col. Jerry O'Hara said. The two wounded soldiers were hospitalized in stable condition, he said.
A local official, Ahmed Jan, said the blast occurred on a road leading to a polling center, just before a convoy of election workers was about to pass, carrying ballot papers.
He said two other roadside bombs were found and defused in the area.
An explosion of household gas occurred in a nine-storeyed apartment building in the city of Shakhty, the Rostov region of Russia. The blast destroyed two storeys of the building
